Boston Calling is at it again, this time announcing the lineup for the fourth installation of Boston’s newest music festival before the third even takes place in May. According to Boston Calling organizers the upcoming incarnation of the festival, set for May 24 – 26 is almost sold out. Organizers are already ahead of the curve, announcing the stacked lineup for September this morning.

Back again for September is The National, whose front man Aaron Dessner has helped curate the first three editions. Joining The National are big names like Lorde, The Replacements, Nas with the Roots, Childish Gambino, Sky Ferriera, the 1975 and Neutral Milk Hotel. Other acts include Spoon, Girl Talk, Twenty One Pilots, Lake Street Dive, who notably originated in Boston, and The War on Drugs to name a few.

Crash Line Productions and Boston Calling co-founder Mike Snow said the decision to release the lineup early was two-fold.

"We were able to get a jump on the May festival, announcing the lineup early and that let us get ahead with September for the most part," he said in an interview on Wednesday, Apr. 23. "The other reason is we wanted to announce ahead of the start of summer. This city and people in general are super busy over the summer so we wanted to allow people to make plans and look ahead to September."

As for the May edition of Boston Calling – featuring Death Cab for Cutie, Modest Mouse, The Decemberists, Edward Sharpe, The Head and the Heart and many more – it’s almost sold out, according to Snow.

"I’d say it’s about 80 percent gone," he said. "We’re out of single day passes for Saturday and Sunday, but there are some left for Friday. Otherwise, we have a limited number of weekend passes still left."

Snow said the September time frame was perfect for scheduling.

"We were able to talk to a lot of bands that will be doing the bigger festivals during the summer," he said. "We’ve got a diverse mix of bands. People needing their EDM fix will have Girl Talk. Also, we really worked hard to get Nas and The Roots together, which we’re all very excited for."

Settling into their second year of large scale music productions, Snow said his team is focused on improving the experience for fans in subtle ways.

"We’ve got a great team in place and we’re unveiling a new video package for the May festival," he said. "We’ve got a great site and that’s allowed us to make small changes and evolve to best suit the people."

"We’re just humbled that Boston Calling has been embrace and allowed to grow," he added. "We just want to present a great experience in Boston’s backyard."

This lineup is undoubtedly our most exciting one yet and I'm looking forward to returning with The National to play a full headline set with full production for our fans in Boston."
